After some research on whether to choose an HK or Dubai server, I went with the HK one to cater to both Asia and the West. The speed is great throughout Asia, and I hope my customers in the US and EU have a similar experience (though I haven't tested it there yet).

I enjoy the analytics feature with notifications, which gives me control over who accesses my files, and when and where they are accessed. The founder is open to suggestions and has a positive attitude. I hope Sinosend lasts for a long time!
